This invention relates to a dumping vehicle and has for its objecttoprovide a vehicle, as for example a motor or horse drawn truck, with asimple, inexpensive, easily operated body memher which may be tipped todump its load without any effort upon the part of the-operator of thevehicle, or without'utilizing any mechanism actuated by the vehicledriving mechanism.

The invention consists of a dumping vehicle as set forth in thefollowing specification and particularly as pointed out in the claims.

Referring to the drawing:

Fig. 1 represents a side elevation of a rear portion of a vehiclechassis including a dumping body member embodying my invention.

Fig. 2 is a side elevationof the rear portion of I the vehicle chassisillustrating the body member in a tipped position.

Fig. 3 is a detail transverse section taken on the line 9-9 of Fig. 1.

Like numerals refer to like parts throughout the several views of thedrawing.

In the drawing, 5 represents the chassis of a truck of conventional typeprovided with side frame members 6 and a floor l or other suitablesupporting structure for a pair of parallel tracks 9 which extendfrom-the rear of a cab l for said truck to the rear end of the floor I.The tracks 8 are inclined, sloping downwardly slightly from their frontends toward their rear ends. The chassis 5 is provided with a bodymember'9 of any suitable construotiom'to the under side of a floor ll)of which are secured a plurality of bearing members ll upon' whichflanged wheels l2, l3, ll, l5, l9 and I1 arerotatably mounted. A set ofthe wheels l2 to H inclusive are provided for each side of the bodymember 9 to rest upon each track 9, and said wheels increase in diameterslightly from the rearmost wheels I 2 toward the foremost wheels I 1 ina manner to increase the inclination of the body member 9 upon theinclined tracks 8. The body member 9 is locked in its forward positionand also prevented from lifting oil! the tracks 9 at its forward end bya. locking bar l9.

Secured to the under side of the floor l0 adjacent to opposite sidesthereof and at points midway between the front and rear ends of the bodymember 9 are pivot members l9 having a flat surface 20 embodied thereinwhich contacts with the floor I of the chassis at the rear end thereofduring the dumping operation after the wheels l2, l9 and I4 have becomedisengaged from the tracks 8. The rearward movement of the body member 9during the dumping'operation is restricted as maybe desired by chains 2|pro-' vided at opposite sides of said body member and secured at theirforward ends to posts 22 pro-,

vided upon the chassis. It will be understood that the effective lengthof the chains 22 may be varied and that an increase or decrease in thelength of said chains will change the tipping position of the bodymember. During the dumping operation the flat surfaces 29 of the pivotmembers l9 engage the rear end of the floor I of the chassis asillustrated in Fig. 2 and a restricted sliding contact is permittedbetween the pivot members and said floor.

It will be evident that the dumping action of v the body member will beinfluenced considerably by the weight distribution of the load withinsaid body member. After the load has been dumped the body member 9 mustnecessarily be lifted by the operator, but the weight distribution ofthe empty body member is such that it is easily returned to the tracksand pushed upwardly to the position illustrated in Fig. 1.

I claim:

1. The, combination-with a vehicle chassis of tracks mounted thereon andsloping downwardly toward the rear thereof, a body member, a pinralityof wheels attached to said body member.

and arranged to support the latter upon said tracks, and pivot memberssecured at an interthe rearmost wheels toward the foremost wheels,

and pivot members secured at an intermediate position beneath said bodymember upon opposite sides thereof arranged to pivotally contact withthe rear extremity of said chassis and also to slide thereupon duringthe tipping movement of said body member upon the chassis.

3. The combination with a vehicle. chassis of tracks mounted thereon andsloping downwardly toward the rear thereof, a body member, a pluralityof wheels attached to said body memberand arranged to support thevlatter upon said tracks, said wheels increasing in diameter from therearmost wheels toward the foremost wheels, and pivot members secured atan intermediate position beneath said body'member upon opposite sidesthereof and provided with flat surfaces arranged to pivotally contactwith the rear extremity of said chassis and also slide thereupon duringthe tipping movement of said body member upon the chassis.
